A Store for hierarchical data. Parent-Child relationships are tracked
internally, and can be accessed through the getParent(Object) and
getChildren(Object) calls, and modified through the many add()
overrides or the remove(Object) method.
As with ListStore, all changes and data are relative to what is
currently visible, due to the Store.StoreFilters. As such, if filters
are active and structural changes are required, it might be necessary to
disable filters to make the change, re-enabling them when finished.
